Guys, thank you so much for helping, but the error was all on my end. This
morning I’ve looked at my krb5.conf and noticed this:
[domain_realm]
.ubuntu.oleg.com = OLEG.COM
ubuntu.oleg.com = OLEG.COM
instead of
[domain_realm]
.oleg.com = OLEG.COM
oleg.com = OLEG.COM
Once I changed it all went fine!
Cheers
Oleg
